BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to display technical field, especially toa pallet and a packaging case.

2. Description of Related Art

With the appearance and development of various types of liquid crystalproducts, the liquid crystal display has penetrated into every industryand every corner of the social life. In a liquid crystal display (LCD),the key component is a liquid crystal panel. In the fabrication for theLCD, because of the division of work, a large number of the liquidcrystal panels are transported to other places for the next step of amodule process.

In the prior art, as shown in FIG. 1 to FIG. 3, before transporting alarge number of the liquid crystal panels, multiple liquid crystalpanels 11′ are installed into a packaging box 1′ in batches. Besides,after a buffer pad 12′ is disposed below each of the liquid crystalpanels 11′, the multiple liquid crystal panels 11′ are placed into thepackaging box 1′ (as shown by an arrow “a” in FIG. 1), and are placedabove a pallet 2′. After a case cover 3′ covers the latest packaging box1′ of the multiple stacked packaging box 1′, using a wrapping belt 4′ tofix the packaging boxes 1′ so as to form a packaging case 5′. Thedisadvantages by above way are: 1. the structure of the pallet 2′ usedfor loading the packaging boxes 1′ is a plane, and the plane is onlyused for stacking the packaging boxes 1′ having the liquid crystalpanels 11′ inside; therefore, the plane does not have a function forpackaging the products. 2. after the packaging boxes 1′ are stacked, thestability depends on the wrapping belt 4′, the friction between a bottomsurface of the lowest packaging box 1′ and the surface of the pallet 2′;when the packaging case 5′ are vibrated and shaken in a truck during thetransportation process, and when shaking force is larger, the lowestpackaging box 1′ will slide relatively to the pallet 2′ such that thepackaging case 5′ will be tilted; the adjacent packaging cases 5′ maybump with each other or hit the inner wall of the truck such that aportion of the packaging case 5′ suffer a larger force; as a result, theliquid crystal panels 11′ inside the packaging box 1′ is damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Preferred embodiments are described below with reference to thedrawings.

With reference to FIG. 4 to FIG. 9, embodiments of a pallet of thepresent invention are shown.

As shown in FIG. 4, FIG. 4 is a perspective diagram of the palletaccording to a first embodiment of the present invention. The palletprovided by the first embodiment of the present invention is used forfixing multiple packaging boxes 2. A bottom box surface 21 of eachpackaging box 2 is provided with a recess 211. The pallet 1 comprises atop pallet surface 11 for engaging with the packaging box 2, a bottompallet surface 12, and an outer side wall 13 disposed between the toppallet surface 11 and the bottom pallet surface 12. The pallet 1 isusually made of a plastic material, a wood material or a metal material.A cross section of the packaging box forms a square shape, a rectangularshape, or a polygonal shape.

Wherein, the top pallet surface 11 includes a pallet recess portion 111having an upward opening formed by caving toward the bottom palletsurface 12, and a pallet protrusion installing surface 112 formedsurrounding the pallet recess portion 111. The pallet protrusioninstalling surface 112 provides with at least one pallet protrusion 113used for engaging with the recess 211 of the bottom box surface 21 ofthe packaging box 2. Wherein, after the multiple liquid crystal panels 6disposed with buffer pads 7 below are installed into the pallet recessportion 111 (as shown by an arrow “b” in FIG. 6), the pallet protrusion113 is engaged with the recess 211 of the bottom box surface 21 of thepackaging box 2 (as shown by an arrow “c” in FIG. 9). As a result, thepallet 1 has a carrying function, and can limit the packaging boxes 2 tomove on the top pallet surface 11.

In order to better limit the movement of the packaging boxes 2 on thetop pallet surface 11, the pallet protrusion 113 is formed by extendingupwardly with a certain length along an inner wall edge 114 of thepallet recess portion 111, and the pallet protrusion 113 is engaged withthe recess 211 of the bottom box surface 21 of the packaging box 2. Thecross-sectional contour of pallet protrusion 113 formed by extendingupwardly along an inner wall edge 114 of the pallet recess portion 111is consistent with the cross-sectional contour of packaging box 2.Besides, some slide preventing structures such as a folding structurecan be disposed on a portion of the pallet protrusion installing surface112 which is contacted with the bottom box surface 21 of the packagingbox 2 so as to increase the friction force between the bottom boxsurface 21 of the packaging box 2 and the pallet protrusion installingsurface 112. As a result, the stability of the packaging case stacked bythe packaging boxes 2 is increased.

After the aforementioned packaging boxes 2 are stacked and covered witha case cover 3, the outer side walls 13 is provided with a cavity 131formed through the outer side walls 13 such that a packaging belt 4 canpass through the cavity 131 and surround the packaging case 5 so as tofirmly fix the case cover 3, the multiple packaging boxes 2, and thepallet 1 (as shown in FIG. 7). For convenience, the cavity 131 has anopening toward the bottom pallet surface 12, and two terminals of theopening of the cavity are respectively communicated with the outer sidewall 13 of the pallet 1.

Corresponding to the pallet provided by the first embodiment of thepresent invention, as shown in FIG. 7 to FIG. 11, the second embodimentof the present invention provides with a packaging case. The packagingcase comprises the pallet 1 described in the first embodiment of thepresent invention, the case cover 3, and the multiple packaging boxes 2disposed between the pallet 1 and the case cover 3. Wherein, the pallet1 has the same configuration and connection relationship as the palletdescribed in the first embodiment of the present invention.

Each of the packaging boxes 2 includes a bottom box surface 21 and a topbox surface 22. The bottom box surface 21 is provided with a recess 211.The top box surface 22 comprises a box recess portion 221 with an upwardopening and formed by caving toward the bottom box surface 21, and a boxprotrusion installing surface 222 formed surrounding the box recessportion 221. A box protrusion 223 is disposed on the box protrusioninstalling surface 222 for engaging with the recess 211 of the bottombox surface 21 of the adjacent packaging box 2. Between two adjacentpackaging boxes 2, after the recess 211 of the bottom box surface 21 ofone packaging box 2 engages with the box protrusion 223 of the top boxsurface 22 of the other packaging box 2, the movement of the twoadjacent packaging boxes 2 is limited so as to increase the stability ofthe multiple packaging boxes 2 after being stacked.

In order to better limit the movement between the adjacent two packagingboxes 2, the box protrusion 223 is formed by extending upwardly from theinner wall edge 224 of the box recess portion 221, and the boxprotrusion 223 is capable of engaging with the recess 211 of the bottombox surface 21 of the adjacent packaging box 2 (as shown in FIG. 10).

Furthermore, the pallet protrusion 113 of the pallet 1 has the samestructure as the box protrusion 223 of packaging box 2 so as to avoidchanging the structure of the recess 211 of the bottom box surface 21 ofthe packaging box 2 in order to save the cost.

Furthermore, the packaging box 2 is made of a plastic material, a woodmaterial or a metal material.

Furthermore, the case cover 3 is made of a plastic material, a woodmaterial or a metal material.

The pallet and the packaging case provided by the embodiments of thepresent invention have the following advantages:

In the embodiments of the present invention, because the pallet recessportion of the pallet can install a production material (such as theliquid crystal panel), the bottom surface of the pallet recess portioncan use as the bottom box surface of the packaging box so as to save thematerial for the packaging box, reduce the packaging cost. Besides,because the pallet protrusion installing surface of the pallet isdisposed with the pallet protrusion, and the pallet protrusion iscapable of engaging with the recess of the bottom box surface of thepackaging box, the movement of the packaging boxes is limited so as toincrease the stability of the packaging case stacked by the packagingboxes, decrease the damage of the production material (such as theliquid crystal panel) in the transportation process.
